Review: Under the Nocturnal Emissions alias, Nigel Ayers has been making inspired sound art and experimental ambient music since 1980. In that time, he's put out many fantastic releases, with 1988's cassette-only "Spiritflesh" amongst the most beguiling. Here issued on vinyl for the very first time, the album sees Ayers and a small group of collaborators create woozy ambient soundscapes out of a limited range of instruments and a large number of manipulated and processed field recordings (according to Mannequin's accompanying liner notes, these are mostly of various animals and birds, though such is the tape trickery you can barely tell). The results remain utterly spellbinding, as if Chris Watson had sat down with Brian Eno to create something magical out of his noted nature recordings.
